In a preference aggregation setting, a group of agents must jointly make a decision, based on the individual agents’ privately known preferences. To do so, the agents need some protocol (or mechanism) that will elicit this information from them, and make the decision. Examples of such mechanisms include voting protocols, auctions, and exchanges. In most real-world settings, preference aggregati...

This research focuses on improved force-reflecting teleoperation system control in free motion and contact tasks. Specifically, the Naturally-Transitioning Rate-to-Force Controller (NTRFC) is implemented in an Air Force experimental force-reflecting teleoperation system to: 1) achieve a unified controller with no mode switches from free motion to contact; and 2) reduce the wrench exerted on the...

This paper analyzes the problem of …rms that need to make investment decisions in capital markets characterized by trading frictions and ex-post bargaining. Trading frictions make switching from one capital supplier to another costly, thus implying that the match between …rms and suppliers generates surplus. Ex-post bargaining implies that suppliers can appropriate part of this surplus. Firms r...

This study examined Super’s (1990) concept of recycling through the stages of adult career development in a sample of 226 Australian men and women who were approximately evenly distributed across the following four steps in the uptake of a second career: (a) contemplating a change, (b) choosing a new field, (c) implementing a change, and (d) change fully completed. A group of adults of similar ...

This study aims to explore users’ image seeking behaviour when searching for known, non-annotated images across languages in FlickLing. In particular, the investigation reported in this paper aims to demonstrate the value in focusing on user’s trust and confidence in the exploration of seeking behaviour to reveal users’ perceptions of the tasks involved when searching across languages. The task...

Despite the aphorism, “Nature does not make jumps,” it is frequently useful to work, either descriptively or prescriptively, with simplified models which involve switching between different modes of evolution. We describe a variety of examples of such modeling with particular attention to some situations in which the interpretation of the reduced model is a matter of concern.
